摘　　要：设置了燕麦3个播种量(103.2 kg/hm^2、154.8 kg/hm^2、206.4 kg/hm^2)和饲用豌豆3个播种量(120 kg/hm^2、180 kg/hm^2、240 kg/hm^2),分析了播种量对南方冬闲田种植燕麦和饲用豌豆的产量的影响。结果表明:燕麦和饲用豌豆的干草产量随着播种量的增加而增大,播种量大的2个处理显著高于播种量最小的处理(P<0.05)。通过1 m垄段的株数与干草产量回归方程分析,燕麦和饲用豌豆的干草产量随着株数的增加而提高;当株数达到一定量后,燕麦产量呈下滑态势,相关系数为0.764(P<0.01),饲用豌豆产量趋于平稳,上升幅度不大,相关系数为0.683(P<0.01)。Three sowing rates of Avena sativa L.（103. 2 kg/hm^2,154.8 kg/hm^2,206.4 kg/hm^2） and Pisum arvense L.（120 kg/hm^2,180 kg/hm^2,240 kg/hm^2） were set up to analyze the effects of sowing rate on the hay yield of these two forage grass crops planted in winter fallow fields in southern China. The results showed that the dry hay yield of A. sativa and P. arvense increased with the increase in sowing rate,and the two treatments with larger sowing rate obtained significantly higher dry hay yield than the treatment with minimum sowing rate（P〈0.05）. The results of regression analysis indicated that： the dry hay yield of both A. sativa and P. arvense in 1-m ridge increased with the increase in the seedling plant number in 1-m ridge; after the plant number reached a threshold,the dry hay yield of A. sativa decreased（correlation coefficient was 0. 764,P〈0. 01）,while that of P. arvense tended to be stable（correlation coefficient was 0.683,P〈0.01）.
